Abstract

Photoconductive antennas (PCA) are promising candidates for high-resolution imaging applications. They have been investigated in transmission when the receiver is a power detector. Here we consider another PCA as the receiver and develop a model of the quasi-optical (QO) coupling between the transmitter and receiver under pulsed laser illumination. Specifically, a field matching technique is used to evaluate the open-circuit voltage of the receiver. Based on this voltage, the spectral mutual coupling between the two PCAs, including the QO path can be evaluated. A bow-tie antenna feed is used as an example to show the coupling coefficient.
